Answer:
The correct answer is: A) Those that are cephalized.
Explanation:
<u>The Central Nervous System is only present in animals that are </u><u>cephalized, capable of moving, and have bilateral symmetry</u>.
Cephalized animals have a proper region in their front end in which the mouth, the sensory organs and the nerve ganglia concentrate and form a "head".
An animal with bilateral symmetry has a single plane of symmetry (the sagittal plane) which divides the body into two halves: one left and one right.
Animals that are radially symmetrical exhibit a pattern around their central axis that repeats itself up to 8 times. A good example of a radially symmetrical animal is a starfish.
Answer: The curvature of the crystalline lens increase
Explanation:
Since accommodation is the ability of the eye lens to change in shape so as to focus on an object. So, when we look at a far-away object, the ciliary muscles relaxes and moves away from the lens making the suspensory ligaments tight, pulling the lens, and causing its crystalline curvature to become thinner (decrease), so that light rays passing through it are bent less enabling them to focus on the retina.
However, the reverse happens when the human eye focus is switched to a near object, such that: ciliary muscles contracts, suspensory ligaments slackens, and crystalline lens becomes more curved (increase)
Thus, the change in accommodation makes the curvature of the crystalline lens to increase
Answer: it releases CO2 into the atmosphere
Explanation:
Cellular respiration is the process by which organic sugars are broken down to produce energy.
